Definitions

  • the present invention relates to a machine for handling fragile products such as curd used in the manufacture of cheese.
  • the curd is a very fragile product which must be handled with great care so that the quality of the resulting cheese is an. It is precisely to take account of this imperative that its introduction into the cheese molds is sometimes still ensured manually, according to the technique known as ladle molding.
  • the present invention proposes to overcome the drawbacks of the ladle molding technique while retaining the advantages and, to do this, it relates to a machine which is characterized in that it comprises a horizontal plate connected to a support movable vertically and horizontally, at least one hemispherical or substantially hemispherical cap suspended from the plate with its inlet facing downwards, a flap of a shape similar to the cap and articulated thereon around two diametrically opposite pivots provided at the entrance of the latter, this volat being movable between a closed position in which it extends under the cap while its inlet is turned upwards and an open position in which it covers the cap while its inlet is turned downwards , and means for moving the shutter between its open and closed positions.
  • This machine allows the curd to be handled with care and delicacy, which reduces the proportion of cheeses downgraded for broken and crushed cheese. It also allows better productivity and therefore contributes to lowering manufacturing costs.
  • the flap consists of two parts symmetrical relative to the median plane of the cap which passes through the two pivots.
  • the means for moving the flap between its open and closed positions preferably comprise a rod disposed vertically above the top of the cap and provided at its lower part with a yoke carrying an axis parallel to the two pivots , two levers articulated on the axis of the yoke and whose lower ends are connected to the two parts of the flap respectively by two axes arranged symmetrically with respect to the axis of the two pivots, and means for moving the rod relative to the plate between a low position in which the flap is in its closed position and a high position in which the flap is in its open position.
  • the upper ends of the levers extend above the axis of the yoke and each carry an elastic pad capable of being compressed against a stop carried by the rod, when the latter is in its high position.
  • the elastic buffers prevent the shutter from remaining inadvertently in its open position when the rod moves to its low position and consequently increase the operational safety of the machine.
  • the rod is connected to a horizontal console located above the plate and movable vertically relative to the latter under the control of a drive member.
  • the opening and closing of the shutter can thus be ensured by moving the console relative to the plate, which can be achieved in a simple manner, for example using hydraulic or pneumatic cylinders, rod-crank systems, etc. ..
  • the means for moving the shutter between its open and closed positions comprise a vertical rod whose lower end is connected to the inlet of the shutter by an axis parallel to the two pivots and equidistant from these, two parallel rods located one above the other, these rods being rotatably mounted around two horizontal axes extending above the pivots and being each pivotally connected to the rod, and means control to rotate the rods alternately about 180 ° in each direction so as to alternately move the flap from its open position to its closed position.
  • the axes of rotation of the rods are carried by supports fixed to the plate, on either side of the latter.
  • control means comprise two identical pinions wedged on the axes of rotation of the rods, an intermediate pinion wedged on the plate and in engagement with the two pinions, and means for connecting one of the pinions in rotation to a member. engine.
  • the cap has at least one vent at its upper part.
  • the air contained in the cap can thus escape freely while it is immersed in the quail.
  • the quantities of quail removed can therefore be equal to the total volume mixed by the cap and the flap, which further improves the efficiency of the machine.
  • the cap contains parallel plates in contact with its inner surface and shaped to be with that of the flap when the latter is in its closed position.
  • FIGS. 1 to 4 The machine that can be seen in Figures 1 to 4 comprises a horizontal plate 1 connected in a manner which will appear clearly below to a support 2 secured to a carriage not shown movable both vertically and horizontally. It also includes a certain number of hemispherical caps 3 distributed in rows, these caps being suspended from the plate 1 so that their inlet 4 (visible in FIGS. 2 to 4) is turned downwards.
  • the plate supports four rows of caps each having five identical caps. It goes without saying, however, that the number and distribution of the caps could be different without departing from the scope of the present invention.
  • Each cap 3 comprises a flap 5 of hemispherical shape, articulated around two pivots 6 provided at two diametrically opposite points of its inlet 4 and consisting of two parts 5a, 5b symmetrical relative to the vertical plane passing through the two aforementioned pivots.
  • the flaps 5 can be moved between a closed position (visible in FIGS. 1 to 3) in which they extend under the cap on which they are hinged, their inlet 7 being turned upwards, and an open position (visible in the Figure 4) in which they cover the cap in question, their inlet 7 then being turned downwards.
  • a closed position visible in FIGS. 1 to 3
  • an open position visible in the Figure 4
  • each of them is controlled by means comprising a rod 8 (particularly clearly visible in FIGS.
  • the two levers 11 connected to the same flap are bent in the vicinity of their lower end to take account of the fact that the axes 12 are adjacent to the inlet 7 of this flap.
  • the pads 13 come against a stop 14 provided inside the yoke 9 and subject the two associated levers 11 to a slight elastic deformation by which the flap is not likely to remain open when the rod 8 returns to its low position.
  • the rods 8 are slidably mounted in sleeves 15 retained in holes made in the tray 1 and are all connected to a horizontal console 16 located above it, their upper end comprising a threaded part extending above the upper face of the console and receiving two locking nuts 17.
  • console 16 is fixed to the lower end of columns 18, for example four in number, protruding under the support 2, these columns being slidably mounted in guide sleeves 19, the l the lower end is fixed against the upper face of the support 2 and the upper end of which is fixed against the lower face of a plate 20 parallel to the support 2.
  • the console 16 On its upper face, the console 16 also carries a central yoke 21 on which is articulated one of the ends of a connecting rod 22 passing through the support 2, this connecting rod being articulated at its other end on a crank pin 23 carried by an arm 24 integral in rotation with a pulley 25 which is rotatably mounted in a yoke 26 fixed on the upper face of the support 2 and which is connected by a belt 27 to a drive member not shown.
  • each of the caps 3 is connected to the plate 1 by two vertical columns 28 arranged symmetrically with respect to the corresponding rod 8, the lower end of these two columns being welded to the cap while their upper end has a threaded portion extending above the upper face of the plate and receiving a clamping nut 29.
  • caps 3 contain three parallel plates 30, 31, 32 in contact with their inner surface and shaped to be with that of the corresponding flap 5 when the latter is in its closed position. These plates, which are preferably removable, are intended to fractionate the product during its removal, and more precisely to promote the exudation of the serum contained in the curd when the machine according to the invention is used for the manufacture of cheese.
  • FIGS. 5 to 7 show a hemispherical cap 3 comprising a hemispherical flap 33 in one piece.
  • This flap is articulated around two pivots 34 provided at two diametrically opposite points of its inlet 35, which makes it possible to move it between a closed position (visible in FIGS. 5 and 6) in which it extends under the cap 3 while that its entry is turned upwards, and an open position (visible in FIG. 7) in which it covers the cap while its entry is turned downwards.
  • the means provided for moving the flap 33 between its open and closed positions comprise a vertical rod 36, the lower end of which is connected in the vicinity of its inlet 35 by an axis 37 parallel to the two pivots 34 and equidistant therefrom, two parallel rods 38 , 39 located one above the other, these rods being rotatably mounted around two horizontal axes 40, 41 extending above the pivots 34, and being each pivotally connected to the rod 36, and control means for alternately rotating the rods approximately 180 ° in each direction.
  • the axes 40, 41 are carried by upper 42 and lower supports 43 fixed respectively on the upper and lower faces of the plate 1.
  • the cap 3 is connected to the lower supports 43 by two vertical columns 44 carrying the pivots 34 at their lower end.
  • control means of the links 38, 39 they comprise two identical pinions 45, 46 wedged on the axes 40, 41, an intermediate pinion 47 wedged on the plate 1 and meshing with the two pinions 45, 46, a pulley 48 coaxial with and integral in rotation with the pinion 45, and a transmission not shown connecting the pulley 48 to a drive member also not shown.
  • the cap 3 has at its upper part a vent 49 premitting the air which it contains to escape during the removal of the curd.
  • the present invention also relates to a basin making it possible to remove practically all the curd which it contains, this basin being essentially characterized in that its bottom comprises substantially hemispherical depressions, such as those represented at 50 in FIG. 1 and whose distribution corresponds to that of the caps 3 suspended from the plate 1.
